DescriptionPlants of CHAMPS have a runner growth habit. Main stem height (297 mm) is slightly shorter than NC 7 (330 mm) (Wynne et al., 1979) or Wilson (322 mm) (Mozingo et al., 2004), equal to NC-V 11 (297mm) (Wynne et al., 1991), but taller than VA 98R (282 mm) (Mozingo et al., 2000). Pod characteristics such as shape, size, and bright color make CHAMPS ideal for the in-shell trade. Measurements of pod brightness were determined by a colorimeter using Hunter L scores (higher number indicates brighter pod color). CHAMPS has similar scores to VA 98R and Wilson, slightly brighter pod color than NC-V 11 and much brighter than NC 7 for both the jumbo and fancy-sized pods. Total kernel content of CHAMPS averaged approximately 1 to 4% higher than other cultivars tested. The blanchability of CHAMPS is equal to popular Virginia-type cultivars (Mozingo, 2004). CHAMPS (20 hits 24 m-1) is similar to Wilson and VA 98R (22 and 19 hits 24 m-1, respectively), but is lower than NC-V 11 (26 hits 24 m-1) in susceptibility to sclerotinia blight (caused by Sclerotinia minor Jagger). For tomato spotted wilt virus (TSWV) caused by Tospovirus, CHAMPS is equal to NC-V 11 (the most TSWV resistance large-seeded Virginia-type cultivar currently available) in susceptibility (24% of row with symptoms for each cultivar). However, CHAMPS showed less susceptibility than either Wilson or VA 98R (both with 29% of row infection) to TSWV. Although not selected for resistance to cylindrocladium black rot (CBR) caused by Cylindrocladium parasiticum Crous, Wingfield, and Alfenas, CHAMPS has tolerance similar to that of Wilson which is rated as moderately resistant. CHAMPS with 37% infected leaflets is not as susceptible as Wilson (44%), NC-V 11 (69%) or VA 98R (81%) to web blotch caused by Phoma arachidicola Marasas, Paver, & Boerema,. Susceptibility of CHAMPS to other diseases and insects has not been observed. Based on general observations, CHAMPS responds to recommended insect and disease control practices as well as other released Virginia-type cultivars. CHAMPS matures early and has excellent yield potential when harvested around 140-145 days after planting in Virginia (normally around September 25 to October 1).
